A few days before you intend to plant the seed, buy ripe passion fruit from the store. Open it and collect at least 6 seeds. Spread the seeds out onto burlap and rub them until the juice sacs burst open. Wash the seeds in water and allow them to dry for 3 to 4 days before washing them again and drying them in the shade. If you plant the seeds immediately, they should germinate within 10 to 20 days. If you need to store the seeds, place them in airtight plastic bags and refrigerate them for up to 6 months.
Fill the container with a soil mixture made from equal parts compost, topsoil, and coarse sand. Fill the container with 4 inches (10 cm) of this mixture.
These furrows will serve as shallow drains that can help prevent moisture from drowning the seeds or their budding roots.
Immediately water after planting the seeds. Moisten the soil, but do not drench it. After planting the seeds, all you need to do is provide an occasional sprinkle of water when the surface of the soil dries out.
Cuttings get most of the moisture they need to grow from humidity since they do not have roots at this point. As such, you do not want to use a soil that will retain a lot of moisture.
Newer growth is more active, so it is recommended that you choose a newer portion of vine rather than an older portion. Immediately plant this cutting into your sand bed. Remove the bottom-most leaves to help your cutting preserve water.
Make sure that any humidity chamber you use stays moist. Keep it in full sun, and place it where the air is moist. If you need to generate additional humidity, you can do so by running a humidifier or by placing dishes of water-covered gravel around the base of the cutting.
“Full sun” means a full 6-8 hours of sunlight daily, if not more. The area should also be free of weeds. If there are a few weeds, make sure that you remove them before planting. The vines need space to climb and spread, as well. Ideally, you should look for climbing structures already set in place, like a wire fence, balcony, or pergola. If none of these are available, you could install a trellis, instead. If the vines have nothing to climb, they will start wrapping around the tree.
Mix the soil with compost before you do any planting. Compost improves both the texture and nutritional value of the soil. You could also try organic rotten manure, leaf mold, or other green plant waste. If the soil is especially dense, you could lighten it by mixing in a handful of coarse sand. Pay attention to the pH of the soil, as well. The pH should be between 6. 5 and 7. 5. If the soil is too acidic, mix in ground dolomite or agricultural lime. Add compost to your soil every year to keep it regularly amended. Mix organic matter or sand into your soil to keep it well-drained.
Carefully dig or slide the passion fruit seedling and its root system out of the container. Place the root system in the center of the hole, then loosely fill in the rest of the hole with soil until the plant feels secure. Handle the roots as little as possible during the transfer. The roots are very sensitive, and if you damage them during the process, you could destroy the plant.
The entire root system needs access to the fertilizer and mulch. For best results, gently push or dig some of the cover into the top layer of the soil after spreading the fertilizer and mulch around the plant’s base.
You should apply fertilizer in the spring and once every four weeks throughout the summer season. A final feeding should also be done in the mid-autumn. Use organic, slow-release fertilizers that are low in nitrogen. Chicken manure pellets are a good option. If the area you live in gets plenty of rainfall, you might not need to water the plant too often. If you are going through a drought, though, or if you only live in moderately moist conditions, you will need to water the vine at least once a week. Never allow the surface of the soil to completely dry out.
Training the vines is a fairly simple process once you get the hang of it. When fresh vines or feelers begin to stretch out, tie the vine around its base and around the wire of your structure using thin rope or string. Keep the knot loose to avoid choking the vine. When the plant is new, lateral branches that come from the main stem should be nipped off to the level of the wire. The two side branches coming from the main stem should then be bent around the top wire of your structure and forces to grow in opposite directions. Once the side branches are spread apart, lateral branches can develop from them and hang down loosely.
Keep 2–3 feet (0. 61–0. 91 m) of space around each side of the vine base weed-free. Use organic methods of weed removal and do not use chemicals. Mulch can help prevent weeds from shooting up out of the ground, and hand-pulling weeds that do sprout is another good option. The rest of the garden can have other plants and weeds in it, but you should keep away plants that could spread disease or attract pests. Legume plants, in particular, are dangerous to keep around passion fruit plants.
Prune in the spring every second year. Make sure that you do so before the plant flowers. Pruning after flowering has occurred can weaken the plant and limit its fruit yield. Use shears to cut away branches that are below 2 feet (61 cm). Doing so clears away weak, old growth while also improving air circulation around the bottom of the plant. [3] X Research source When pruning, make sure that you are not removing a major branch by following the stem along to its base before you cut it away. Leave three to five nodes near the base of a branch when you cut it off. New growth can emerge from the stump this leaves behind.
To hand-pollinate the plants, take a small, clean paintbrush and collect the pollen from male flowers. Wipe the collected pollen onto female flowers using the same brush. You could also touch the anthers and stigmatic surfaces of each flower with your thumb and index finger as you walk along the rows.
The biggest pest-related problems are aphids, vine girders, and coleopteran beetle larva. Aphids can usually be discouraged by sprinkling red pepper around the base of the plant or by spraying them with a focused stream of water from your hose. Get rid of vine girders by mixing an organic insecticide in a tar base. Spread this solution around the base of the main stem, and get rid of damaged vines. To get rid of beetle larva, you will need to use a systemic insecticide before the plant goes to flower.
Passion fruit vines can fall victim to rot and viral diseases. Cellar rot and root rot must be prevented ahead of time by providing adequate soil drainage. You can attempt to treat virus-infected plants with a commercial solution, but usually, you will need to cut off and burn the affected vines in order to preserve any of the remaining plants. Passion fruit mottle virus, passion fruit ringspot virus, and cucumber mosaic virus are your most common threats.
Typically, ripe passion fruit will drop from the vine as soon as they are ready for consumption. The drop itself does not hurt the fruit, but you should collect the fruit within a couple of days after it drops to ensure the best possible quality. If you have a variety that does not drop its fruit, simply pluck off each fruit once you notice the skin beginning to wrinkle.
